EL5256

Manufacturer Part Number
EL5256
Description
Manufacturer
INTERSIL [Intersil Corporation]
Datasheet
<1mV Voltage Offset, 600MHz Amplifiers
The EL5156, EL5157, EL5256, and EL5257 are 600MHz
bandwidth -3dB voltage mode feedback amplifiers with DC
accuracy of <0.01%, 1mV offsets and 40kV/V open loop
gains. These amplifiers are ideally suited for applications
ranging from precision measurement instrumentation to high
speed video and monitor applications demanding the very
highest linearity at very high frequency. Capable of operating
with as little as 6.0mA of current from a single supply ranging
from 5V to 12V and dual supplies ranging from ±2.5V to
±5.0V, these amplifiers are also well suited for handheld,
portable and battery-powered equipment. With their
capability to output as much as 140mA, any member of this
family is comfortable with demanding load conditions.
Single amplifiers are available in SOT-23 packages and
duals in a 10 Ld MSOP package for applications where
board space is critical. Additionally, singles and duals are
available in the industry-standard 8 Ld SO package. All parts
operate over the industrial temperature range of -40°C to
+85°C.

... Again, a small series resistor at the output can help to reduce peaking. Disable/Power-Down The EL5156 and EL5256 can be disabled and their output placed in a high impedance state. The turn-off time is about 330ns and the turn-on time is about 130ns. When disabled, the amplifier's supply current is reduced to 17µA typically, thereby effectively eliminating the power consumption ...
